i just recently got my head rebuilt after bending a valve back in march, but long story short i got the car all back together it has low compression wiseco pistons, sleeved, built head and a fuel return setup. the car runs fine but today i had it sitting at idle and i noticed it kept wanting to die and so i got in it and it was flashing the cel like for a misfire. anyone who what could cause suck a thing?

The tune or fuel system, what engine management are you running, also what fuel injectors are you running?

Did you perform a compression and leakdown test?

What's the AFR? Also do a compression test dry then wet compare the numbers to make sure your engine is ok like the last post says.

afr's are on the leaner side at idle but i think it may be because i have an exhaust leak. my s-pipe was modified to fit my down pipe so its a little bit off to the stock header. im still trying to source a stock s pipe or just get a flex s ection added to mine
